Step-by-step explanation:
is 11/8 a rational or irrational number ??
Answer:
Rational number
Step-by-step explanation:
Rational numbers can be written in a way where the entire number is displayed.
Irrational numbers will look a little "weird." They will have a square root or greek letter (such as π) because you cannot display the entire number. It would take forever to write out the number π (3.14159...). So we just use a symbol. That makes it an irrational number.
11/8 is the rational number not a irrational number.
The given number is 11/8.
What are irrational numbers?Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.
The decimal expansion of a given number is
11/8 =1.375
The decimal expansion is terminating decimal number
Therefore, 11/8 is the rational number not a irrational number.

1. Sharon is a good student who enjoys statistics. She sets a goal for herself to do well enough compared to her peers so that her standardized score on her Statistics final is equal to her percentile rank (written as a decimal) among her classmates. What goal did she set for herself
The available options are:
(A)0.25
(B)0.78
(C)1.09
(D)2.25
(E)2.41
Answer:
(B)0.78
Step-by-step explanation:
Given the fact that percentile rank is usually between 0 to 100. Hence, considering the available options, the 100th percentile would be converted to 1.0 when representing the percentile into decimal places.
Since it is logically and mathematically impossible to go beyond the 100th percentile, hence, the option C, D, and E are wrong.
Also, since Sharon hoped to get a score well enough compared to her peers, then the correct answer is 0.78 which can be translated to 78 percentile. Because 0.78 is a better score than 0.25 or 78 percentile is better than 25 percentile because 78 percentile means she scored better than 78 percent of all the test takers.
Hence, the right answer is in this case is 0.78

A car is 180 inches long.A truck is 75% longer than the car
How long is the truck?
A construction crew is using heavy equipment to dig a hole in which the foundation of a house will be built. The hole
will be in the shape of a right rectangular prism with dimensions of 4 feet in depth, 100 feet long, and 50 feet wide.
The soil will be removed using a truck that can hold a maximum of 40,000 pounds. The soil weighs 90 pounds per
cubic foot. What is the least number of truckloads needed to remove all of the soil?
Answer: 5
Step-by-step explanation: volume of hole = 100x50x4=20,000 ft
soil weighs : 20000x90=180,000 pounds
180,000 divided by 40,000 = 4.5 ≈ 5
So the least number of truckloads is 5
This year, a small business had a total revenue of $18,700. If this is 15% less than their total revenue the previous year, what was their total revenue the previous year?
Answer:
The business's total revenue the previous year was $22,000.
Step-by-step explanation:
Since the business's revenue is 15% less than it was the previous year, we can subtract that 15% from 100% to see what percentage of last year's revenue is the business getting now.
100% - 15% = 85%
So the business is getting 85% of what it got last year. We also know that this small business is getting $18,700 this year.
So really, this question is asking 18,700 is 85% of what?
Y = P% of WHAT?
18,700 = 85% of X
18,700 = 0.85 · X
Now that we have set this equation up, we solve for x. To get x alone, you must divide by 0.85 on both sides.
18,700 ÷ 0.85 = 0.85 · X ÷ 0.85
Simplified, this is 22,000 = X
So their total revenue the previous year was $22,000.
This is not the only way to do this - there are others, but this is one of the easiest to understand is more efficient.
Answer:
$21,505
Step-by-step explanation:
$18,700×115%=$18,700×115/100
=$21,505

The mean length of 6 rods is 44.2 cm. The mean length of 5 of them
is 46 cm. How long is the sixth rod?
===============================================
Work Shown:
x = sum of all 6 lengths
x/6 = mean of the 6 lengths
x/6 = 44.2
x = 6*44.2
x = 265.2
All 6 lengths add up to 265.2 cm.
---------
y = sum of the first 5 lengths
y/5 = mean of those first 5 lengths
y/5 = 46
y = 5*46
y = 230
The first five lengths add up to 230 cm.
---------
z = length of the 6th rod, length is in cm
y+z = (length of first 5 rods)+(length of 6th rod)
y+z = x
230+z = 265.2
z = 265.2-230
z = 35.2
The sixth rod is 35.2 cm

A 40 g ball of yarn is 125 m long. What is the mass of a ball of the same yarn that is 2 km long?
Answer:
640g
Step-by-step explanation:
1000m=1km so 125m times x= 2km x is 16 so we multiply 16 by 40 to get 640 g
The mass of 2 km long yarn ball is 640.
What is mass?A measure of how much matter is in an object. This gold bar is quite small but has a mass of 1 kilogram (about 2.2 pounds), so it contains a lot of matter.
Given
40 g ball of yarn is 125 m long
To find mass for 2 km = 2000 m long yarn
[tex]\frac{40}{125} \ 2000[/tex] = [tex]\frac{80000}{125}[/tex] = 640g
Hence, The mass of 2 km long yarn ball is 640.

What is p rounded to three decimal places?
Answer: p= 0.644
Step-by-step explanation:
We know that, the confidence interval for population proportion is given by :-
sample proportion(p) ± Margin of error(E)
Given confidence interval : (0.61,0.678)
i.e. p- E = 0.61 ... (i)
p+E = 0.678 ...(ii)
Adding (i) and (ii), we get
2p = 1.288
p= 0.644
From (ii),
E= 0.678-0.644
E= 34
Hence, the value of p = 0.644

Step-by-step explanation:
the answer is 0.2
The average of x and y is 03
How to determine the average?The average of the three numbers is given as:
Average = 10
This means that:
(x + y + 24)/3 = 10
Multiply both sides by 3
x + y + 24 = 30
